In the drawings, I have illustrated my improved printing apparatus as applied to an automatic printing and weighing apparatus, but it will be understood that my printing apparatus may be employed with any other suitable device so as to give an indication of a suitable function or a measured condition. The arrangements illustrated in the drawings include a suitable conveyor with a plurality of scales upon which packages may be placed, the weight of which it is desired to be determined and printed on the packages. During the time the scale is coming to rest or reaching its place of balance, the scale will be moved around until the pointer of the scales comes in contact with one of a group of contacts which control the operation of my printing apparatus. The printing apparatus includes a movable member such as a rotatable wheel on the outer periphery of which is placed suitable characters or figures and in the illustrated application numbers would be placed on the outer periphery of the wheel corresponding to the range of weight of the packages being weighed. The rotatable wheel includes a conducting ring member with an outwardly extending finger, the finger being adapted to cooperate with a plurality of contacts which are spaced around a circle. These contacts are in turn connected with the contact which cooperates with the movable pointer of the scale and a second contact is placed to cooperate with the ring of the rotatable wheel. A

suitable control circuit will include the pointer, and the contacts with which it is cooperating at a particular moment and when the rotatable wheel rotates until the finger touches the particular contact connected with the contact which is being touched by the pointer at the particular moment, a wheel arresting arrangement will be operated to relatively rapidly arrest rotation of the wheel. The group of contacts which cooperates with the conducting finger on the rotatable wheel is so positioned with respect to the figures or numbers on the periphery of the wheel that the wheel will be stopped so that the proper number is positioned so that upon bodily movement of the printer the proper number will contact the particular package thus printing the proper weight on the package. It will be understood that in this manner different packages may be successively weighed and the weight thereof printed on the package.-

Referring to Figure 1 of the drawings, I have illustrated a weighing apparatus including a suitable turret mechanism which may take any suitable form and in the construction illustrated in Figure 1, it includes a member having a plurality of outwardly extending bars I on the ends of which are placed Weighing scales I2. A conveyor I3 is suitably positioned adjacent the periphery of the turret Ill so that packages M which it is desired to be weighed may be delivered to the scales as an empty scale is positioned adjacent the end of the conveyor l3. It will be understood that a second conveyor mechanism l5 may periphery of the turret for receiving the packages M from the scales after they have been suitably weighed and the proper weight has been marked on the package. The turret I0 may be operated in any suitable manner such as being mounted on a spindle l6 which spindle is rotated through a disk wheel I! mounted thereon which in turn cooperates with a pinion wheel l8 connected to a shaft Hi. It will be understood that the shaft 9 may be rotated from any suitable source of power (not shown).

It will be understood that after a first package I4 is delivered to an adjacent empty scale l2 for a short length of time after the package is delivered onto the scale, the scale will oscillate thus causing a pointer thereof to oscillate until it comes to rest thus giving an indication of the weight of the package on the scale at that particular moment. In order, therefore, to insure that the scales have come to rest and the pointer is stationary with respect to the scales, my improved printing apparatus which is indicated generally by the numeral 2| in Figure 1 is positioned so that the turret must travel at least a portion of a complete revolution before the package l4 which has been deposited on a particular scale is in position adjacent the printing device 2| to have the weight of the package on the adjacent scale printed with its weight.

In order to control the operation of the printing device 2| which will be described below, I provide a group of spaced cont-acts indicated generally by the numeral 22 which are positioned rela tive to each other around the arc of a circle which is approximately the same are of travel of the pointer 20 of the weighing machine. It will also be understood after the description of my printing device that there is a particular contact in the group 22 corresponding to each of the numerals or figures which are provided on the outer periphery of the printing device. It will be understood that any suitable number of contacts may be provided depending upon the range of numbers which it is desired to be printed on the package being weighed.

My improved printing apparatus as will be illustrated more particularly in Figures 4 and 5 includes any suitable type of movable member 23 and in th arrangement illustrated in the drawings, the movable member is a wheel or disk which is mounted for rotational movement on a shaft '24. In order to have a minimum amount of friction between the shaft and the rotatable wheel be seen particularly in Figure 6.

4 23, a suitable bearing 25 may be provided between the wheel and the shaft 24. A sleeve 26 is provided adjacent one surface of the Wheel so as to prevent the wheel from having axial movement along the shaft 24. The wheel may be rotated in any suitable manner and in the construction illustrated in the drawings, the wheel is rotated through an electric motor 21 which is mounted on a suitable stand 28 adjacent the outer periphery of the wheel 23. The outer periphery of the wheel 23 is provided with a shoulder 29 upon which a shaft 29 of the motor 2! bears so that upon energization of the motor 21, the wheel 23 will be rotated by the frictional engagement between the rotating shaft 29' and the shoulder 29 of the wheel.

In order that the printing apparatus may print the result of the measured condition such as the weight of the particular object I4 being weighed, the outer periphery of the wheel is provided with a plurality of numbers or figures 30. These figures may be of any suitable type depending upon the condition which is being measured and in the construction illustrated in the drawings, it will be seen that the figures are in the form of numbers and in Figure 5 it will be seen that the numbers are ten pounds, nine pounds fifteen ounces and ten pounds one ounce. When weighing a plurality of objects M the weights of which will run within a predetermined range, suitable figures are provided on the outer peripher of the wheel 23 corresponding to the weights within the range which it is expected the objects M will run.

In order to provide a suitable arrangement for arresting the rotational movement of the rotating wheel 23 at predetermined positions, I provide similar tracks 3| on the opposite radial extending edges of the wheel 23. It will be understood that the tracks 3| may take any suitable shape and in the construction illustrated in the drawings, they have approximately a sinusoidal shape with hills 3 la and valleys 3|b as will Cooperating with these tracks 3|, I provide track following members 32 which have at their outer ends ball bearings 33 which follow the hills and valleys of the tracks as the wheel '23 is rotated. Any suitable type of follower may be provided and a ball bearing construction 33 is an efficient arrangement since a' minimum amount of friction will be presented with this type of construction. The ends of the bars 32 are supported in cantilever fashion by members 34 which are pivotally mounted at the opposite ends in bearings 35. Guide members 36 are placed on either side of the pivotally mounted bars 34 so as to maintain their oscillatory movement in a predetermined path. During a portion of the cycle of operation of the weighing cycle the bars 34 will merely oscillate back and forth an amount equal to the depth between the bottom of the valleys 3lb and the top of the hills 3|a. In order to bias the ends of the rods 32 toward the tracks 3|, the opposite bars 34 may be connected together by a suitable spring 31.

In order to provide a force to cause the ends of the rod 32 to be held tightly adjacent the valleys 3|b of the tracks 3| at a particular instant in the cycle of printing and weighing, solenoids 38 and 39 are provided with windings which surround a core leg 40. It will be understood that upon energization of the windings of the solenoids a flux will circulate around the rectangular core which includes the movable rods 34 and thus cause the rods 34 to be tightly held against the end of the winding legs of the core. It will be understood that by designing the size of the solenoids 38 and. 39 with respect to the contour of the tracks 3| and the rotational inertia developed by the rotation of the wheel 23, upon 'energization of the solenoids, the wheel 23 may be made to arrest its operation substantially instantly.

In order to provide a suitable control circuit for arresting the rotational movement of the .printer wheel 23 so that the desirable figure will be positioned to print a facsimile thereof on the package l4 on the adjacent scale, I provide a suitable conducting member 4i on one of the radially extending faces of the wheel. The conducting member may take any suitable shape and in the construction illustrated in the drawk ss, it has a first portion or ring portion Ma and a radially extending bar portion 4lb. Placed around the circumference of the circle having a radius approximately equal to that from the center of. the shaft 24 to the central portion of the bar Mb, I provide a plurality of spaced contact members 42. The contacts 42 may be supported in any suitable manner such as by placing them for limited movement in bores 43 of a disk 44. The outer ends of the bores 43 are closed by conducting members 45 and biasing springs 46 and provided between the ends of the members 45 and the contacts 42. In this manner all the contacts 42 will be biased against the adjacent surface of the disk 23 so that as it rotates the conducting bar 4lb will successively contact each of the contacts 42 as it makes one complete revolution. This may be seen in the diagrammatic representation in Figure 3 where the various contacts 42 are placed around a-circle having a radius R so that as the bar 4lb makes a complete revolution, it will contact successively each of the contacts 42. The disk 44 is also provided with a single bore 41 for containing a contact 48 which is a distance r from the center of the shaft 24. It will be seen that the distance r is the same as the radius of the ring 4| so that the contact 48 will continu- A ously be in contact with the ring 41a.

In order to connect the various contacts into a suitable control circuit, it will be seen from the diagram of Figure 3 that each of the contacts 42 is connected to a corresponding contact 22 through conductors 49. It will be recalled from the description above that the various contacts 22 are the contacts which are selectively contacted by the pointer 20 of the weighing machine depending upon the weight of the particular objects being weighed. The contact 48 which rides on the ring 41a is connected to a suitable control circuit through a conductor 50. This control circuit may be of any suitable type which will relatively quickly operate the coils of solenoids 38 and 39. This is accomplished through a control circuit including a conventional grid controlled electron tube 5! having the plate connected to one Side of the coils of the solenoids 38 and 39 through a conductor 52, the other sides of the coils of the solenoids 38 and 39 being connected to the cathodes of the tube 5| through a conductor 53 and the secondary windings 54 of a power transformer 55. The transformer may also include a heater secondary 56 which is connected to the heater of the electron tube. It will therefore be understood that when the grid of the electron tube is made sufficiently positive, the tube will fire or be rendered conductive and pass current through the coils of the solenoids 38 and 39 thus causing the rotating wheel 23 to be arrested or braked. As will be illustrated in Figure 3, the grid is controlled through a circuit including the conductor which is connected to the grid and to ground through a suitable battery 51. The opposite sides of the pointer 20 and the battery may be grounded and therefore when the pointer 20 contacts a predetermined one of the contacts 22 depending upon the weight of the package being weighed at that particular instant, and when the rotating finger 41b contacts the corresponding one of the contacts 42, current will flow in the grid controlled circuit thus causing the tube to fire.

Operation of my improved weighing and printing arrangement may therefore be summarized as follows: After a particular package M has been introduced upon the turret In from the conveyor l3 and the turret in has been stepped around until that particular package is adjacent the printer 2|, the pointer 20 will have stopped oscillating so as the pointer rides over the spaced contacts 22, it will contact only one of them. The particular contact being contacted by the pointer 20 in Figure 3 is identified by the numeral 22a. Let us assume also that the wheel 23 is rotating in a counterclockwise direction and as soon as the finger 4lb contacts the particular contact 42a which is connected to the contact 22a, a circuit will be completed from ground through the pointer 20 to the contact 22a, through the particular wire 49 to the contact 42a and then through the finger 4lb and ring Mo to the contact 48. The circuit may then be traced through the conductor 59 to the grid controlled circuit and to ground. This will cause a current to flow making the grid less negative and therefore cause the tube to fire. Upon operation of the tube, the solenoids 38 and 39 will be energized, thus arresting or stopping the rotation of the wheel 23 and assuming that the fingers have been suitably positioned on the outer periphery of the wheel, the proper number will be positioned for printing. Let us assume that this number is ten pounds.

In order to print a facsimile of the number ten pounds on the package, relative movement is caused between the package and the printing mechanism and in the construction illustrated in the drawings, the printing mechanism is bodily moved as the shaft 24 is integrall connected to a rod 50 which is pivotally mounted at one end in the bearing 6|. The rod 60 and the printing wheel on one end thereof is caused to oscillate toward the package on the adjacent scale through a solenoid 62 which has an operating member 63 connected to the rod 60 through a strap connection 64. It will be seen from the diagram in Figure 3 that the operating coil of the solenoid 62 is connected in parallel with the operating coils of the solenoids 38 and 39 so that all three solenoids are operated simultaneously. This will cause the wheel 23 to stop rotating as has been described above and also cause bodily movement of the printer wheel toward the package so that a facsimile of the number ten which has been properly positioned will imprint itself upon the package thus indicating on the package that that particular article weighs ten pounds. A suitable spring 65 is provided for retracting the rod 60 into its position so that the shoulder 29 will again be in position to be contacted by the shaft 29' of the motor 21 to again cause rotation of the wheel 23.

Any suitable arrangement may be provided so as to prevent the tube to fire again to cause the printing wheel 23 to be again oscillated toward the same package after it has printed the proper number thereon. Thus, a suitable time delay arrangement may be provided in the electron tube circuit or we may assume that by this time the turret ID has again been caused to rotate so that the pointer 20 drops out of engagement with the particular contact 22a with which it had been in engagement in order to complete the circuit to cause the wheel 23 to be arrested.

Any suitable arrangement may be employed for inking the various numbers on the outer periphery of the wheel and in Figure 4 it will be noted that an ink pct 66 having a roller 61 is positioned so as to maintain a suitable writing fluid on the raised numbers 38 on the outer periphery of the wheel 23.

Referring to Figure 8, I have illustrated the structure of the group of contacts 22 which cooperate with the pointer 20, and it will be understood that the group of contacts may be so constructed that their contacting surfaces will be generally parallel with the plane of movement of the movable pointer 28 as it is rotated around the shaft Hi. It will be seen that the contacts include a plurality of channel-shaped conducting members which are embedded in a suitable insulating block ll. In order to insure that the movable pointer 20 will be guided into one of the contact troughs 10 during its movement, the forward ends of the contact members 18 are provided with insulating pointer portions 12. It will therefore be seen that if the pointer contacts one of the pointed portions 12, it will be guided into 7 one of the trough-shaped contacts 10. It will also be seen from an inspection of Figure 8 that the trough-shaped members 10 have contacting surfaces 10a which are inclined slightly from the plane of the path of movement of the pointer 20, or, in other words, the trough-shaped members 18 will be deeper at the forward ends adjacent the points 72 than they will be adjacent the rear ends. The purpose of this construction is that if the pointer 28 is positioned between the sides of the trough-shaped members 10 and the end of the pointer 28 is slightly bent, since the surfaces 1011 are inclined slightly with respect to the path of movement of the pointer 20, the pointer will contact the surfaces 10a at some point during its travel through the trough-shaped members 10.

It will be understood that any suitable construction may be provided for causing relative movement between the printer wheel 23 and the object upon which a facsimile is to be printed, and in Figure 9, I have illustrated a modification of the construction illustrated in Figures 1 through 7 in which the object upon which it is desired to be printed is a tape which is unwound from a reel (not shown) and wound on a reel 11. A tape of carbon may be provided which is unwound from a reel 16. It will be understood that in the construction illustrated in Figure 9, suitable arrangements are provided for operating the printer wheel 23 until the desired figure is adjacent the tape 15 depending upon the object or condition which is being measured. This condition or function which is being measured may be the weight of packages which are provided on a turret as is illustrated in Figure 1 or may be any other suitable function such as an equivalent number which is on a recording device remote from the printer 23. It will also be seen that an electromagnet 18 is provided having a movable armature 19 so that when the solenoid 18 is operated, the adjacent portion of the tape will be pushed against the proper number through the movement of the armature member 19. It will be understood that the solenoid 18 may be operated in a circuit similar to that which operates the solenoid 62 in Figure 3 for causing relative movement between the printing wheel and the object upon which the facsimile is printed.

It will be understood that the printing wheel may be moved in any suitable manner, and in Figure 10 I have illustrated an arrangement for stepping a printing wheel around to a predetermined position depending upon the measurement of a function the recording of which is desired such as through a printing of the facsimile of a function on a suitable object. Referring to Figure 10, I have illustrated a wheel 80 upon which is provided a plurality of figure 8|, the wheel 80 being adapted for movement around an axis or shaft 82. Attached to the wheel 80 is a ratchet wheel 83 which is adapted to be moved in a stepped manner through a pawl operating member 84. The pawl 84 may be in turn operated in any suitable manner such as through an operating lever 85 which is pivoted at 85 and which is operated when a selector solenoid 8'! is energized. A second pawl member 88 is provided which is biased toward the ratchet wheel 83 through a spring 89, and the pawl member 88 may be moved out of engagement with the wheel 83 when a homing magnet coil 98 is energized. In order to operate the printing wheel 80 back to a predetermined or homing position after it has been moved to a predetermined position through the energization of the selector magnet coil 81, I provide a spring member 92 which is wound up each time the selector magnet 81 is energized and upon energizing of the homing magnet coil 80, the pawl 88 will be moved out of engagement with the ratchet wheel 83 thus allowing the spring to return the printing wheel 80 to a predetermined or homing position at which time a suitable stop 93 will contact the pawl 88.

In order to operate the selector magnet coil 81 and the homing magnet coil 90, I provide a plurality of groups Of contacts which are indicated generally by the numeral 95 in Figure 11. When my improved printing apparatus is employed as an automatic weighing and printing apparatus, the plurality of groups of contacts indicated by the numeral 95 in Figure 11 will take the place of the contacts 22 as is illustrated in Figures 1 and 2. It will be seen that the plurality of groups of contacts 95 include a plurality of groups 95a, 95b, 95c, 95d, and 956, and each one of the groups 95a through 95c have a different number of contacts and in the construction illustrated in Figure 11, th group 95a has seven contacts with each of the remaining groups having one less contact than the preceding group. Each of the adjacent contacts of the various groups is connected together by suitable conductors 96 and the various conductors are in turn connected together through a conductor 91 which connects to the operating coil of the selector magnet coil 81. The circuit is continued through a conductor 99, a suitable source of electric potential I08 such as a battery and a suitable pointer mechanism l0! which may, if desired, be similar to the pointer 20. It will be understood that the pointer mechanism l8| may be operated around its pivot point I02 to a predetermined position in an arc depending upon the particular function which is being indicated or measured, and when the pointer I0! is a part of a weighing scale of the type illustrated in Figure l, the pointer l! will reach a position depending upon the weight of the object in the scale. Let us assume that the end of the pointer is adjacent the group of contacts 95b. It will then be seen that as the pointer is bodily moved in the direction of the arrow which would be substantially the direction in case the pointer were being bodily moved by rotation of the turret around the shaft l6, the end of the pointer IOI will make contact successively with each of the contacts of the group 95, and as each contact is made, the selector solenoid 81 will be energized to cause the printing wheel 80 to be rotated one step. It will be understood that for each step in its rotation, another number will be suitably positioned adjacent an object upon which a facsimile of the number is to be printed such as an object as is shown in Figure 1 or a tape as is shown in Figure 9. After the pointer I 0| has contacted four of the contacts of the group 95b, it will then contact a contact indicated by the numeral I03 which is connected with similar contacts of the other groups in circuit with a solenoid operated coil I04; It will be understood that this solenoid operated coil will cause relative movement between the wheel 80 and the object upon which the facsimile of the adjacent number is printed, and in case it is desired to print on a tape, the coil I04 would be similar to the operating coil of the magnet 18 in Figure 9.

In order to return the printing wheel back to a predetermined or homing position after the printing operation is complete, it will be noted from Figure 11 that each of the groups of contact 95a through 95c is provided with contacts I05. It will be noted that the contacts H05 are connected together through a conductor I06 and to the operating coil of the homing magnet 90, and this coil is also connected through the source of supply I00 and the pointer NH, and upon the pointer contacting the particular contacts I05 of the groups, the pawl 88 will be raised, thus causing the spring 92 which has been wound up due to the inching or stepping movement of the wheel 80 to quickly return the wheel 80 to its homing position or until the stop 93 contacts the pawl 88. The printing wheel will therefore be in its predetermined position so that it can print again whenever the pointer IOI contacts the various contacts of any one of the groups 95a through 95c.

As will be seen in Figure 9, a suitable mask I01. may be provided between the printer 23 and the object on which the number is printed, the mask having a suitable slot to insure that only one number at a time is printed on th tape.

It will, of course, be understood that various details of construction may be varied through a wide range without departing from the principles of this invention and it is, therefore, not the purpose to limit the patent granted hereon otherwise than necessitated by the scope of the appended claims.
